AUSTIN, Texas — Astronomers from The University of Texas at Austin and Germany’s Max Planck Institute for Extraterrestrial Physics (MPE) recently found a surprise when studying some of the oldest star clusters in our galaxy. The stars at the centers of these clusters are rotating around a common axis. It was previously thought any central rotation would have been long erased, leaving the central stars to random orbits. The work has been accepted for publication in the Astrophysical Journal Letters.

AUSTIN — A team of researchers led by University of Texas at Austin astronomer Ivan Ramirez has identified the first “sibling” of the Sun — a star that was almost certainly born from the same cloud of gas and dust as our star. Ramirez’ methods will help other astronomers find other “solar siblings,” work that could lead to an understanding of how and where our Sun formed, and how our solar system became hospitable for life. The work will be published in the June 1 issue of The Astrophysical Journal.

FORT DAVIS — McDonald Observatory announced the winners of its art contest for school kids in Jeff Davis, Presidio, and Brewster counties at its Open House on April 26. The contest, part the observatory’s year-long celebration of its 75th anniversary, received 127 entries in two categories (junior high-high school and elementary school). They were judged on creativity and representation of the spirit of the anniversary celebration.

The University of Texas System Board of Regents Friday authorized UT Austin to spend $50 million to participate in building the Giant Magellan Telescope project, which will be the world’s largest telescope when it’s completed in 2020. The project will give students, researchers and faculty the opportunity to make groundbreaking discoveries in astronomy.

AUSTIN — The upcoming world’s largest telescope has passed two critical milestones, according to founding partner The University of Texas at Austin. The Giant Magellan Telescope (GMT) has passed major reviews on its design and cost estimates and is ready to proceed to construction.

Astronomer Taft Armandroff has been appointed the new director of The University of Texas at Austin’s McDonald Observatory in Fort Davis, Texas.

Armandroff, who is currently director of the W.M. Keck Observatory in Mauna Kea, Hawai’i, will join the university in June 2014.

He succeeds David Lambert, who, as the observatory’s third director, propelled the observatory to national prominence. Lambert will resume his position as a full-time faculty member in the Department of Astronomy.

AUSTIN, Texas — University of Texas at Austin astronomer Steven Finkelstein has led a team that has discovered and measured the distance to the most distant galaxy ever found. The galaxy is seen as it was at a time just 700 million years after the Big Bang.

A pair of recently published studies shed light on the study of the exploding stars known as supernovae. One of these teams includes University of Texas at Austin supernova expert and professor J. Craig Wheeler.

“We are in a new world of identifying supernova progenitor stars and the explosions very early, allowing more thorough study,” Wheeler said. “The event iPTF13bvn allowed both,” he added, referring to the study published September 20 in The Astrophysical Journal.
